6.4.3 Ethernet Standards 6.4.3 Ethernet Standards Ethernet standards are defined by the work of the IEEE 802.3 committee. The following table compares the characteristics of various Ethernet implementations. Category Standard Bandwidth Cable Type Maximum Segment Length Ethernet 10BaseT 10 Mbps (half duplex) 20 Mbps (full duplex) Twisted pair (Cat3, 4, or 5) 100 meters 10BaseFL 10 Mbps (multimode cable) Fiber optic 1,000 to 2,000 meters Fast Ethernet 100BaseTX 100 Mbps (half duplex) 200 Mbps (full duplex) Twisted pair (Cat5 or higher) Uses 2 pairs of wires 100 meters 100BaseFX 100 Mbps (multimode cable) Fiber optic 412 meters Gigabit Ethernet 1000BaseT 1,000 Mbps (half duplex) 2,000 Mbps (full duplex) Twisted pair (Cat5 or higher) 100 meters 1000BaseCX (short copper) Special copper (150 ohm) 25 meters, used within wiring closets 1000BaseSX (short) Fiber optic 220 to 550 meters depending on cable quality 1000BaseLX (long) 550 meters (multimode) 10 kilometers (single-mode) 10 Gigabit Ethernet 10GBaseT 10 Gbps (full duplex only) Twisted pair (Cat6, or 7) 100 meters 10GBaseSR/10GBaseSW Multimode fiber optic 300 meters 10GBaseLR/10GBaseLW Single mode fiber optic 10 kilometers 10GBaseER/10GBaseEW Single mode fiber optic 40 kilometers You should also know the following facts about Ethernet: • The maximum cable length for UTP Ethernet "T" implementations is 100 meters for all standards. • Ethernet standards support a maximum of 1024 hosts on a single subnet. • You may also see 10Base2 and 10Base5 Ethernet implementations, both of which are older implementations using coaxial cable.

6.4.3 Ethernet Standards6.4.3 Ethernet StandardsEthernet standards are defined by the work of the IEEE 802.3 committee. The following table compares the characteristics of various Ethernet implementations.
Category Standard Bandwidth Cable Type Maximum Segment Length
Ethernet10BaseT 10 Mbps (half duplex)
20 Mbps (full duplex) Twisted pair (Cat3, 4, or 5) 100 meters
10BaseFL 10 Mbps (multimode cable) Fiber optic 1,000 to 2,000 meters
Fast Ethernet100BaseTX 100 Mbps (half duplex)
200 Mbps (full duplex)Twisted pair (Cat5 or higher) Uses 2 pairs of wires 100 meters
100BaseFX 100 Mbps (multimode cable) Fiber optic 412 meters
Gigabit Ethernet
1000BaseT
1,000 Mbps (half duplex)2,000 Mbps (full duplex)
Twisted pair (Cat5 or higher) 100 meters1000BaseCX (short copper) Special copper (150 ohm) 25 meters, used within wiring closets
1000BaseSX (short)Fiber optic
220 to 550 meters depending on cable quality
1000BaseLX (long) 550 meters (multimode)10 kilometers (single-mode)
10 Gigabit Ethernet
10GBaseT10 Gbps (full duplex only)
Twisted pair (Cat6, or 7) 100 meters10GBaseSR/10GBaseSW Multimode fiber optic 300 meters10GBaseLR/10GBaseLW Single mode fiber optic 10 kilometers10GBaseER/10GBaseEW Single mode fiber optic 40 kilometers
You should also know the following facts about Ethernet:
• The maximum cable length for UTP Ethernet "T" implementations is 100 meters for all standards. • Ethernet standards support a maximum of 1024 hosts on a single subnet. • You may also see 10Base2 and 10Base5 Ethernet implementations, both of which are older implementations using coaxial cable.
